Maturity: Lm ? range ? - ? cm
Max length : 200 cm TL 雄鱼/尚未辨别雌雄; (Ref. 4408); common length : 100.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 9784)
背棘 (总数): 17 - 19; 背的软条 (总数): 16-17; 臀棘 1; 臀鳍软条: 16 - 17; 脊椎骨: 34. Two lateral lines, originating above the upper angle of gill opening, branching below the 4th dorsal-fin spine or slightly behind it, upper line running along the first dorsal-fin base and ending below about the end of the first dorsal fin, lower line abruptly curved backward from bifurcation, running mid laterally to the base of the middle caudal-fin ray. Body color is dark brown with slightly metallic reflections, sometimes slightly paler on belly. Dorsal fin membranes with black markings.
二条侧线, 开始在鳃裂的上面角上面, 在第 4根背鳍棘下分枝或些微地在它后面, 上面的线沿着第一背鳍基底而且在到处下面终止第一背鳍的末端, 突然地从分叉向后地弯曲的低线, 连续侧面中央地中央尾鳍鳍条的到基底。 体色深褐色的有略微金属的反光, 有时些微较灰白在腹面上。 背鳍薄膜有黑色的斑纹。
Mesobenthopelagic, down to depths of 400 m or more, often at the surface at night around Okinawa, Japan (Ref. 6181). The largest populations are probably on the slope of seamounts or ridges (Ref. 6181). Feeds on a variety of mesopelagic fish, squid and crustaceans (Ref. 6181).
中层大洋底栖性鱼种, 向下至深度 400个公尺或更多, 时常在水表面在晚上日本琉球的周围.(参考文献 6181) 最大的族群可能在海洋山脊或脊的斜坡上。 (参考文献 6181) 吃多种中层带鱼，乌贼与甲壳动物。 (参考文献 6181)
